Question

the elongation of the leading strand during dna synthesis
produces okazaki fragments
depends on the action of dna polymerase
occurs in the 3 → 5 direction
progresses away from the replication fork

Explanation:

• Okazaki fragments are produced on the lagging strand, not the leading strand.
• DNA synthesis (including elongation of the leading strand) occurs in the \(5'\to3'\) direction.
• The leading strand is synthesized continuously towards the replication fork.
• DNA polymerase is the enzyme that adds nucleotides to the growing DNA strand (leading strand elongation depends on its action).

Answer:

B. depends on the action of DNA polymerase
